Abstract
The utility model relates to a wastewater treatment system, it includes aeration tank and filtering ponds. This wastewater treatment system's aeration tank is through sinking sand and aeration, can make solid impurity deposition most in life, the construction sewage in the bottom of aeration tank, plays preliminary solid -liquid separation's effect, and simultaneously, the aeration tank can provide the aerobic environment for the aquatic microorganism, is convenient for have oxygen partial pressure to separate, has also suppressed the anaerobic effect, is favorable to reducing malodorous production. Filtering ponds pass through the multi -stage filtration unit and filter, can obviously improve the quality of sewage discharge, reduce organic matter content. But this wastewater treatment system wide application is closed in various lives, construction sewage disposal field, like power transmission and transformation engineering project's job site, can directly use on -the -spot raw and other materials, it is like preparation such as dumped template, safety net, river sand, stones, with low costs to can use back recycle in the construction, need not other purchase.
Description
Technical field
This utility model is related to sewage purification field, especially relates to a kind of sewage disposal system.
Background technology
Sanitary sewage produced by most job sites (as power transmission project construction field etc.) does not pass through substantially at present
Any process is directly discharged to periphery natural environment, is that nature water environment brings a certain degree of pollution.Workmen's day
The sewage that often life produces is one of primary pollution source of natural water, and main source is feces and wash water.According to statistics, often
The daily sanitary sewage amount discharged of people is 150～400L, wherein contains large amount of organic, such as cellulose, starch, saccharide and fat
Protein etc.；Also the microorganisms such as pathogen, virus and parasitic ovum are often contained；And the chloride of inorganic salts, sulfate, phosphorus
Hydrochlorate, bicarbonate and sodium, potassium, calcium, magnesium etc..Sanitary sewage easily pollutes to natural water especially drinking water sources,
As following various pollutions.
(1) pathogen pollution
The feature of pathogenic microorganism is：1. quantity is big；2. it is distributed wide；3. the time-to-live is longer；4. reproduction speed is fast；5. easy
Produce resistance, be difficult to eliminate；This pollutant enters human body actually by number of ways, and survives in vivo, causes human body
Disease.
(2) aerobic Organic Pollution
The common feature of Organic substance is, after these materials are directly entered water body, to be divided by the biological chemistry action of microorganism
Solve as simple inorganic substances carbon dioxide and water, need to consume the dissolved oxygen in water, under anoxic conditions in catabolic process
Just there is corrupt decomposition, deteriorate water quality in pollutant, often these Organic substances are called aerobic Organic substance.In water body, aerobic Organic substance is got over
Many, oxygen consumption is also more, and water quality is also poorer, illustrates that water pollution is more serious.
(3) eutrophication pollution
Body eutrophication is a kind of excessively caused water pollution phenomenon of the plant nutrient substance content such as nitrogen, phosphorus.Water
The eutrophication of raw ecosystem can be occurred by two kinds of approach by chemical pollutant：One kind is by limiting plant under normal circumstances
The increase of the amount of the inorganic nutrient substance of thing；Another kind is the increase by the Organic substance as decomposer.
(4) acid, alkali, salt pollution
Acid, alkali pollution make water body pH change, and destroy its cushioning effect, eliminate or suppress the growth of microorganism, hinder
The self-purification of water, also corrodible bridge, ship, fishing gear.Acid and alkali often simultaneously enter same water body, can produce some after neutralization
Salt, in terms of pH value angle, acid, alkali pollution self-cleaning because of neutralization, but produce various salts, become the new dirt of water body again
Dye thing.Because the increase of inorganic salt can improve the osmotic pressure of water, there is harmful effect to limnobioss, plant growing, in salinization of soil
Area, the salt in the surface water, subsoil water will endanger soil quality further.
Additionally, sanitary sewage is nitrogenous, sulfur-bearing and phosphorous height, under the anaerobic bacteria effect in natural environment, easily give birth to stench,
Natural environment and human body all can be worked the mischief.
